Sorry to hear that you received that error. I would suggest checking your graphics card. Please make sure that your graphics card can handle what Autocad is throwing at it. I would also check your drivers and make sure that you have installed and are running the latest driver for your graphics card. It could also be a corrupt file. If that happens you will want to AUDIT and RECOVER the drawing file. Another option would be to uninstall and reinstall the .NET framework. A link on how to do that step is provided below.
